Review: Did not need for my truck - I bought this for my 2003 Dodge Ram 2500 5.7 l. I did not realize I would not need it. The actual thermostat comes with the gasket on it so this was actually not needed on my particular model. Seems like a good quality gasket though.
Review: Comme l`original. - Contrairement à la description ce n est pas un kit de 6 clés mixtes, mais un joint d`étanchéité. Fait le travail comme l`original. Aucune fuite. Mais il est installer que depuis 6 mois sur un Dodge Ram 1500 5.7 Hemi 2005.
